Without this fix, running the full LGTM suite would get the IR evaluated
twice. That's because we have multiple IPA types and constructors with
the same name (like `TInstruction` and `MkIRFunction`), and the QL
compiler chooses how to disambiguate those names differently depending
on import order.
I've tested that the IR is only evaluated once now by running the whole
suite on a tiny project (jbj/magicrescue) and looking at the output of
perl -ne 'print if /^RESULTS IN:/ .. /^\[/ and not /^\[/' runSnapshotQueries-debug.log | sort |uniq -c |sort -n |less
